Dependence of the soils’ elastic modulus reinforced with inorganic binders on compressive strength
Introduction. The modulus of elasticity refers to one of the main physical and mechanical characteristics of reinforced local grounds. Deformations of soils and building materials are usually described by Hooke’s law. The main laboratory testing methods include applying of uniaxial compression, tria...

| description | Introduction. The modulus of elasticity refers to one of the main physical and mechanical characteristics of reinforced local grounds. Deformations of soils and building materials are usually described by Hooke’s law. The main laboratory testing methods include applying of uniaxial compression, triaxial compression, rigid stamp technics. Determining the modulus of elasticity is a complex, time-consuming and labor-intensive test. There are empirical models that describe the relationship between the modulus of elasticity and various parameters and characteristics (compressive strength, binder content in the mixture, etc.). However, these models are mainly developed for stabilized soils and for crushed stone reinforced with Portland cement. Methods and materials. To determine the pattern of change in the modulus of soils’ elasticity reinforced with inorganic binding materials from compressive strength, studies were conducted on samples of various soils strengthened with Portland cement and lime. Existing methods specified in the regulatory and technical documentation were used to produce the samples. Results. Based on the performed research, two empirical models were developed that reflect the dependence of the elastic modulus values on the compressive strength values of soils reinforced with Portland cement and lime. Discussion and conclusions. Existing testing methods of the elastic modulus are lengthy and labor-intensive. The developed empirical models allow us to obtain approximate values of the elastic modulus from the values of compressive strength of soil samples reinforced with Portland cement and lime. |
